You know how when you are on a really long line, the ones where you wait for an hour or more? Funny how you start developing short relationships with people on the line. Do you play that game where you make up stories about people too? Not mean stories necessarily, just stories to pass the time.
Being on a long line is actually quite similar to a little temporary neighborhood. A diverse assemblage of people that all for some point in time live in the same, limited demarcation of geography and have to come together to create a sociosphere (I made that word up).
